THE MAXIMUM ECHO AREA OF IMPERFECTLY CONDUCTING DIPOLES.
Abstract
Recently, the question has often been raised as to when the effects of imperfect conductivity must be taken into account when studying the echo area of a wire scatterer such as the dipole. This paper clearly shows the conditions under which the echo area is sensitive to the conductivity. Curves for imperfectly conducting resonant dipoles are presented that show the dependence of the maximum echo area upon conductivity, frequency and dipole diameter. The maximum echo area is defined to be the peak echo area at first resonance. The maximum echo area is related to the penetration of the electric field into the dipole. This makes it possible to obtain a universal curve that may be used to determine the maximum echo area of a specified dipole without actual computation of its resonance curve.
